Tailoring Stereomicroscope Magnification rau ntau daim ntawv thov xav tau
Lub luag haujlwm tseem ceeb ntawm lub phaj polarizing nyob rau hauv lub polarizing microscope yog hloov lub teeb ntuj yam tsis muaj polarization rau hauv lub teeb polarized, tso cai rau lub teeb perpendicular mus rau hluav taws xob hluav taws xob kom dhau mus thiab ua kom lub LCD vaj huam sib luag tso saib cov duab ib txwm. Lub luag haujlwm tseem ceeb ntawm lub polarizer yog hloov lub teeb ntuj dhau los ntawm nws mus rau hauv lub teeb polarized. Polarizing zaj duab xis yog ib daim ntawv -zoo li cov khoom siv kho qhov muag uas tsim thiab pom lub teeb polarized. Polarizing zaj duab xis yog ib feem tseem ceeb uas cuam tshuam cov nyhuv ntawm cov ntxaij vab tshaus LCD.
Polarizing daim hlau yog ib yam khoom uas polarizes ntuj lub teeb yam tsis muaj polarization, hloov nws mus rau hauv lub teeb polarized. Ua ke nrog cov khoom sib tw ntawm cov kua siv lead ua kua molecules, lawv tswj kev hla ntawm lub teeb, yog li txhim kho kev xa tawm thiab saib lub kaum sab xis, thiab tsim cov haujlwm tiv thaiv glare. Lawv yog cov khoom tseem ceeb nyob rau hauv cov khoom siv raw khoom ntawm cov vaj huam sib luag thiab suav txog li 10% ntawm tus nqi ntawm LCDTV raw khoom.
Polarizers cais los ntawm kev ua haujlwm: transmissive polarizers, reflective polarizers, semi transmissive thiab semi reflective polarizers, compensating polarizers
Polarizers yog cais los ntawm txoj kev staining:
Iodine raws li polarizing zaj duab xis: Nws yog ib qho yooj yim kom tau txais high transmittance thiab siab polarization optical zog, tab sis nws muaj peev xwm tiv taus kub thiab high humidity yog tsis zoo.
Dye raws li polarizing zaj duab xis: Nws tsis yog ib qho yooj yim kom tau txais high transmittance thiab siab polarization optical zog, tab sis nws muaj kev tiv thaiv zoo rau kub thiab av noo.
Kev sib xyaw ntawm polarizing zaj duab xis
Cov zaj duab xis polarizing ntxov tshaj plaws yog tsim los ntawm PVA zaj duab xis uas tuaj yeem tsim lub teeb polarized nyob nruab nrab, thiab TAV tiv thaiv zaj duab xis sib xyaw ntawm ob sab. Txhawm rau ua kom yooj yim siv thiab ua tiav qhov sib txawv ntawm qhov muag pom, cov khoom siv polarizer yuav tsum ua kom tau raws li cov kev cai ntawm LCD cov chaw tsim khoom, thiab siv lub siab- nplaum nplaum rau ob sab, ua raws li cov yeeb yaj kiab tso tawm. Hom polarizer no feem ntau siv TN zoo tib yam tag nrho kis tau tus mob polarizer. Yog tias ib txheej ntawm cov yeeb yaj kiab tso tawm raug tshem tawm thiab lwm txheej ntawm cov yeeb yaj kiab tau ntxiv, nws yuav yog ib qho kev cuam tshuam tsis tu ncua.
Lub siab-sensitive nplaum siv yog siab- kub thiab noo- pov thawj siab- rhiab nplaum, thiab PVA raug rau kev kho tshwj xeeb impregnation (dye series khoom), uas ua rau lub dav kub hom polarizer; Ntxiv cov khoom uas tiv thaiv ultraviolet rays tsis dhau los ntawm lub siab -sensitive nplaum siv yuav ua tau UV resistant polarizing films; Los ntawm kev sib xyaw ua ke ntawm birefringent optical them nyiaj zaj duab xis rau ntawm qhov chaw sib kis, ib zaj duab xis polarizing rau STN tuaj yeem ua tau; Lub kaum sab xis polarizer lossis lub kaum sab xis nqaim tuaj yeem ua los ntawm kev sib xyaw ua ke ntawm lub teeb tig zaj duab xis rau ntawm cov yeeb yaj kiab xa tawm; Xim lub siab- cov nplaum nplaum, PVA zaj duab xis lossis TAC zaj duab xis siv yog hu ua xim polarizer. Qhov tseeb, nrog kev txhim kho tas mus li ntawm cov khoom siv LCD tshiab, hom polarizing films kuj nce.
